Running AC on battery power

For those days when the pets have to stay in the RV, and the CG charges extra for electricity. Is it safe to unplug the shore power while you're out while leaving the AC on for the pets and then plugging back in when you return? Or will the batteries drain before the end of the day?

Just curious that you can plug in at night, but not during the day...Doesn't the campground charge the same rate weather you plug in all day or just at night?

Crrier Air V 13,500 btu draws 13.5 amps at 120 volt, that is roughly 135 amps at 12 volt.. I have about 420 amp hours of battery at the 20 hour rate at 135 amps they might last 10 minutes. no more.
Home was where I park it. but alas the.

EVEN if you install a HUGE inverter for the task, unless you carry four or five hundred pounds of batteries you won't have any luck. If you DO have sufficient battery power you better match it with a HUGE battery charger or plan on taking a month bringing them all back to full charge.
Over all, just not practical. Remember dogs and cats didn't HAVE access to air conditioning until about the mid 50s so they managed to survive very well without that convenience (just as their owners did)
Good luck / Skip

1,560 v/a (per hour)

139 amp hours unreachable level of efficiency

End of day 8 hours?

139X8 = 1,112 theoretical amp hours

Battery discharge limit 50% means a 2,224 amp hour battery bank

(20) golf car batteries

And this is just theory. Now comes inverter losses, and the rest of reality.

Won't it be fun trying to not melt the campground grid trying to recharge those 20 batteries? Oops I forgot. Reality. THIRTY batteries would be more like it.

Not at all feasible to run A/C on batteries. ๐Ÿ˜ž

IF you are leaving pets in rig unattended.......at least provide them with A/C.
Pay the extra cost.

Don't know what type/size/number of batteries you have OR IF you even have an 'inverter' but I doubt you have more than two 12V batteries in your FW.

Soooooooo.......No 120V AC power then no Air Conditioner.
Is it time for your medication or mine?

No, your batteries simply won't handle it for more than a few minutes if the AC even turns on. Your invertor can't handle the load either. Don'teven try it.

The AC will not run without 120 volts.
